A model with n = 65 observations is reported as seen below with tvalues in parentheses. Y is expressed in thousands, X1 in hundreds, X2 in thousands, and X3 in single units.

a. What are the standard errors for each variable?

b. What are the p-values for all variables?

c. What is the adjusted coefficient of determination?

d. Rescale Y into single units. What are the model coefficients and standard errors now? What happened to the R2 value? Why?

e. Rescale X1 into single units. What are the coefficients and standard errors of the model now?
